How to Calculate Percentages: 4 Core Formulas

The word "percent" originates from the Latin per centum, meaning "by the hundred." Here is how to solve each standard percentage problem:

Mode 1: X% of Y

Find Percentage of an Amount

Result = (Percentage × Base Value) ÷ 100

Example: 15% of ₹50,000 = (15 × 50,000) ÷ 100 = ₹7,500.

Mode 2: Increase / Decrease

Percentage Change Between Values

Change % = ((New Value - Old Value) ÷ Old Value) × 100

Example: From ₹50,000 to ₹60,000 = ((60,000 - 50,000) ÷ 50,000) × 100 = +20.00%.

Mode 3: Ratio (X of Y)

What Percentage is X of Y?

Percentage = (Part Value ÷ Total Value) × 100

Example: 250 marks out of 1,000 = (250 ÷ 1,000) × 100 = 25.00%.

Mode 4: Difference

Relative Percentage Difference

Diff % = (|A - B| ÷ ((A + B) ÷ 2)) × 100

Example: Difference between 100 and 125 = (25 ÷ 112.5) × 100 = 22.22%.
